11. PARKS The Hillsborough State Park in

Thonotosassa, Florida, charges an admission
fee of $4 plus a camping fee of $20 per
night. This can be represented by the
function f(x)
20x +4, where f(x) is the total
cost and x is the number of nights spent
camping. What is the value of f(5), which is
the cost of 5 nights of camping? (Lesson 2-1)
A. 80
B. 100
C. 104
D. 120

Answer 1

f(5) = 104

Explanation:

To find the value of f(5), we have to plug in 5 into our equation f(x) = 20x + 4.

f(5) = 20(5) + 4

Following our order of operations, we multiply first, then add to get our answer.

f(5) = 20(5) + 4

f(5) = 100 + 4

f(5) = 104

The cost of 5 nights of camping is $104.
